Reading Polynomial Graphs

Since the change from what I had to the new Common Core standards, I'm having to teach certain topics to younger students who might not have the background my older students had.  Yes, I know, Common Core has been coming for a while but we didn't start using them really till this year.  So I am getting ready to introduce my Algebra I class to polynomials and identifying the increasing and decreasing parts of the graph, max and min, and relative max and min.

While surfing the internet for appropriate materials, I ran across the site Cool Math.  They have a lovely section on graphing polynomials. They use plain English with lots of diagrams and make it easy for my ELL students to follow and understand. 

I'll be using this website next week for my students to study absolute max and min, increasing and decreasing, and relative max and mins.  I do know this website works on iPads.

What is nice is they have material for Pre-Algebra, Algebra, and Pre-Calculus.  I love that the Pre-Calculus section has a couple things on trig, including the unit circle.  Yeah.  This will dovetail nicely with an app I have on the ipads.

It appears there are two math game sites associated with this website.  Some of the games I've seen look really good and I know would work on a computer but will they work on an iPad?  I don't know.  But back to the cool math website.

The Pre-Algebra section matches up quite well with the topics I am due to teach this year so that is awesome.  The Algebra section will provide support for both my Algebra I and Algebra II sections while the Pre-Calculus has topics to match Algebra II and my Pre-Calculus classes. 

I love websites that provide support on more than one math class.  I can assign the topic I need students to read and learn more about.  Cool!
